FMVSS 218: This stands for the U.S. DOT's

the minimum standard requirements for all motorcycle
helmets. Manufacturers must submit their helmets for
compliance testing.
Fairing: An enclosure on the front of the
bike containing the windshield and affording wind
protection to the rider. Can be attached to the
frame and not move or be attached to the fork and
move as the handlebars are turned.
Final Judgement: The written ruling on a
lawsuit by the judge who presided at trial. This
completes the case unless it is appealed to a higher
court. Also called a final decree or final decision.

a motorcycle, or how quickly a rider can
"flick" the bike from side to side in

the front wheel to the motorcycle triple-tree.
Four Stroke Engine: This is the most
common engine design found in street motorcycles
today. It refers to the number of times a piston
moves up and down through each power cycle. 1) A
downward stroke brings in the fuel/air mixture; 2)
an upward stroke compresses the fuel/air mixture; 3)
a downward stroke results when that mixture is
ignited and expands, and finally; 4) an upward
stroke expels the exhaust gases.
Fraud: Occurs when intentional false
statements are made to entice a victim to give up
something of value.
Fuel Injection: A device that serves the
same function as a carburetor, but uses
computer-controlled jets to inject atomized fuel and
air into the air stream going into the engine.
